Raven

"Only one?"

You ask.

"Yes."

The Genie replies.

"Only one."

"Damn."

You sigh.

"If it helps, take all the time you need."

Said the Genie.

"I'm quite literally in no rush."

"Thank you."

With that knowledge in hand you ponder. There are a near infinite amount of animated hotties out there in the multiverse, but because you're only allowed one of them, she has to be extra special.

Then it hits you, that there's really only one right choice. Your childhood crush, the one who made you the man you are today!

"I choose Raven from 'Teen Titans'! The '05 animated version!"

You proclaim with pride.

"Hmmm."

The Genie smirks.

"A man of culture I see. Consider it done!"

He snaps his fingers and everything becomes blindingly bright for a moment. When the brightness subsides for look ahead and for a few seconds forget how to breath as standing in front of you is the thicc 18 year old heavenly body of the half-demon goth queen herself!

You look around for the Genie to thank him but he's nowhere to be found, there's only you and your moody waifu!
